DAHMS, or cotUMizIANA, o trroV p Application led October 9, 192,9.l 'Serial No. 393,34.` K i -My invention relates to chair bucks and more especially to bucks for the accommodation of furniture during the process of manu-Y facture, in whichthe furniture piece may be 2.5 tilted and rotated at various anglesV to permit of easy accessibility, especially to the under 15 niturepierze maybe rotated upon au c A` further object is the provision in a; chair buck of'improved means for holding and rotating a chair or other piece of furniture and for locking the same'in the various positions'. A further object is to provide a chair buck adapted to permit working on various sized pieces. `Other objects and advantgageswvill appear and-Abebrought out more fully in the following specification, reference y being Vhad to the accompanyingr drawings, in which Fig. 1 is a side View of a chair buck embodying my invention, and showing a davenport in place in an inclined posit-ion; Fig. 2 is a side view of the chair buck; Fig. 3 is a top view of the same; and Figs. 4 and 5 are sectional views taken along the lines 4 4 and 5 5 of Fig. 3, respectively.

Referring more particularly to the drawe ings, l show a chair or furniture. buck having a table or platform 10 which is rotatable on a shaft 11 in the top of a pedestal 12. Pedestal 12 has a 'base portion 13 which is preferably circular in form, and a.. journal portion 14 which extends through the aperture 15 in a. base plate 16. Base plate 16 is preferably rectangular 1n form and is preferably secured to a carriage frame or chassis 17, as

by bolts 18. A locking plate 19 is securedy by bolts 2O to the journal portion of the pedestal 12 and provides a bearing Contact 21 with a portion of basev16. Base 13 and base plate 16 are provided with bearing surfaces as at 22, and the arrangement ofthe parts is such that pedestal 12 rotates about a vertical axis, but is prevented by locking adapted to engage teeth 32, anda spring 35 plate 19from separating from base 16. 'Base Y Y 1,3 is provided with van enlargement 23 in which 1s located a. locking pin 24 anda spring T25, under the action of which locking pin24 "is biased downwardly in enlargement 23.

number of apertures 26` are formed in baseplate 16, which napertures are located onia circle of radius equalto that of the radius of pin`-24, so that, as pedestal 12is rotated,lock

ing-pin 24'may drop into successive apertures l 26`to lockthe .pedestal in anyone Vof a'fiium-` ber ofwpositions. "Io` effect'the release ofA i locking` pin 24, I'have-provided a lever 27,

secured as by a bolt 28, to lthe sideof pedestal 12, and lever 27 has-a forkedportion 29 which D passes underthe head'of bolt 30 which is se cured to locking pin 24.

A table 10 is provided with a segmen integrally associated with it, and segment31 has a number of locking teeth 32 out in itscircular periphery. AV locking arrangement forthe segment is provided and consists of'a *chamber 33 located on the side of pedestal 121 and having within it the locking pin 34 is located in chamber 33 and tendslto keen *pin 34 in engagementl with the teeth n i order'to effectfthe release ofA pin 34, a lever bracket 38 and has an engaging link '-39 which l ispivoted to lever36 at 40 and which is jse-v cured to the lower endv of pin 34.k f

I provide for the support and the securing of the' chair or otherV article of furniture to be worked on by the following arrangement Holding plates 43 are secured as by screws 44 tothe tops of'. lugs 41 and effectively'prevent the removal of slides 42. Slides 42V are arrangedinfpairs and are provided with stops 45 which j limitV their movement 1 both inwardly and outwardly.` Beneath the -ta-V blelO and arranged ysubstantially opposite -lugs 41 are llugs 46, provided with cap'plates 47l secured by lscrews similarly to lugs 41, andflugs'4( provide guideways for pairs ofv clamp slides 48. Slides- 48 have their outerr :36 is provided, whichispivoted atx37non aV l ico h piece. 1 Y f c 'Fn'eoperation of the chair buck is as follows: Slides 42 arer iirst Withdrawn the re-` ported on ends 49 by a bolt 51 and these eccentrics 52 each have a clamp 53, and clamps 53 each have a hook portion 54r adapted to xengagethe member 55 of the chair or 'furniture piece 56. Eccentrics 52 consist of a cylinder having a peripheral groove 56 1n which A pair of oppositely ldisposed radial apertures 59 in eccentrics 52 ,arefprovlded, and

these apertures are adapted for a key :by which the eccentrics can be rotated. Table- 10 is providedvvith a number of. slots f6() il p Whichfpermit clamps`53to be admitted for small .sized chairpor :furniture` holding a quired distance and the chair or frame placed on the slides with members 55 ot the frame Y 'across pairs offslides 42, and` slides 48 are 1 Withdrawn the corresponding distance. vClamps 53 lare then hooked over members 55 and, "with the eccentric bolts 51 inserted in 1 the proper aperturesA 50, the eccentric 52 can be turned and its operation will clamp meme` bers 55V firmly to the slides 42; Eccentric bolts 5l being turned past its center will lresult in a locking ac-tionoi vthe clamps.

Vhen itis desiredto turn the article aboutY a vertical aXis, lever 27 can be pressed,
